Daniel Webster had two chances to become president via the vice presidency. In 1840 the Whig party nominated William Henry Harrison for president and Harrison offered the vice presidency to Webster. Webster turned it down and Harrison died after a single month in office; his death would have made Webster president.
Eight years later Webster competed with Zachary Taylor for the Whig party’s nomination. Taylor won and invited him to be his running mate, and Webster again shunned the office, saying, “I do not propose to be buried until I am really dead and in my coffin.” Taylor won the White House and died 16 months afterward, which again would have made Webster president if he’d accepted.
